Yes, Trusted Computing is used for DRM
"Ever since the Trusted Computing Group went public about its plan to put a security chip inside every PC, its members have been denying accusations that the group is really a thinly-disguised conspiracy to embed DRM everywhere. IBM and Microsoft have instead stressed genuinely useful applications, like signing programs to be certain they don't contain a rootkit. But at this week's RSA show, Lenovo showed off a system that does use the chips for DRM after all.
The system is particularly frightening because it looks so simple. There's no 20-digit software key to type in, no dongle to attach to the printer port, no XP-style activation. (Is this what Bill Gates was thinking of when he said in his keynote that security needs to be easier to use?) The user interface is just a Thinkpad, albeit one of the new models with an integrated fingerprint sensor."
